Denisova DNA

The genome sequence of a Denisovan individual was generated from a small fragment of a finger bone discovered in Denisova Cave in southern Siberia in 2008. Approximately 30-fold coverage of the genome was generated using the Illumina GAIIx sequencing platform.

This project aims to convert the massive amount of data of Denisovan Genome to a raw data download file if FTDNA (or) 23andMe did the test. So, basically, I am just extracting the SNPs from Denisovan Genome and constructing the autosomal raw data file. This project is aimed to be more like factoids provided by FTDNA, just doing it from a hobbyist research perspective (and may produce scientific results). So, if you have a long strand/segment match which suggests that you are a cousin to Denisovan, don't blame me ;). The source files are taken from Denisovan DNA in VCF format. I used 2 laptops running 24/7 for nearly 2 weeks to parse ~ 1 terrabyte of Denisovan genome to produce the below results.
